Ive noticed this in the past, but today i noticed it again and wanted to see why.

If i hold my car at say quarter throttle(relaly doesnt matter as long as its a decent acceleration rate) i notice that my car doesnt have a constant pull, Itll pulse. Pulls hard, lets up for a split second then pulls again, over and over and over, its not like complete lack of ignition or fuel or anyhting, i can just feel that it is pulling less. I cant really think of why thou. Any ideas welcome.

 

Check your TPS to see if it's set correctly. Could be that the TPS is sending an erratic signal and telling the ECU that you're on it and off it during the acceleration. You mentioned that it's only at steady-state throttle, and not WOT, so possibly the TPS is set incorrectly.

Take a look and let us know,

 

well i think it does it if i floor it to, but its only when i hold the throttle at a constant point. ill check tps tomorrow morning
